util.xml: Break reference to help the GC (fix #1711)
LuaExpat uses a registry reference to track handlers, which makes
it so that an upvalue like this creates a reference loop that keeps the
parser and its handlers from being garbage collected. The same issue has
affected util.xmppstream in the past.
Code for checking:
local xml_parse = require"util.xml".parse;
for i = 1, 10000 do xml_parse("<root/>") end
collectgarbage(); collectgarbage();
print(collectgarbage("count"), "KiB");
A future release of LuaExpat may fix the underlying issue there.
